Brown corundum grinding wheel shape characteristics

The shape of the grinding wheel mainly includes a flat grinding wheel, a double-sided concave grinding wheel, a double beveling grinding wheel, a cylindrical grinding wheel, a dish-shaped grinding wheel and a bowl-shaped grinding wheel. The grinding wheel is made into various shapes and sizes according to the needs of the machine structure and the grinding process. Table 6 shows the shape, size, code and use of several commonly used grinding wheels. The outer diameter of the grinding wheel should be selected as large as possible to increase the peripheral speed of the grinding wheel, which is advantageous for improving the grinding processing productivity and surface roughness. In addition, under the conditions of machine tool stiffness and power permitting, if the grinding wheel with larger width is used, the productivity and roughness can be improved. However, in the case of grinding heat sensitive materials, in order to avoid burns on the surface of the workpiece and Cracks are generated and the width of the grinding wheel should be appropriately reduced.
